The Observatory is a full-bleed, zero-library WebGPU surface that renders the memory graph as a living cognitive field. Five deterministic demo moments driven by a URL contract (?demo=<name>&seed=...&frame=N): recall-path, engram-birth, salience-rescue, forgetting-horizon, firewall. Capture mode (?frame=N) freezes the sim deterministically so the same URL produces identical pixels, the viral-clip primitive. Architecture: bare-metal WebGPU engine (no Three.js), seeded demo clock, per-demo plan + renderer modules, WGSL shaders (simulate, nodes, edges, path, birth particles, rescue, forgetting, firewall) plus a post-processing chain (tone mapping, MIP). DOM is instrument overlays only (telemetry strip, timeline spine, rescue verdict); the layout gives /observatory the same full-bleed bypass as marketing routes so recordings stay clean. Reads the real memory graph. Verified live: svelte-check 939 files 0 errors, 96 observatory unit tests green, all 5 demos load at 108-119fps with zero console errors against the live brain. Known follow-up: engram-birth capture-mode particle cluster needs a render fix pass before it is camera-ready; the other 4 demos are camera-ready.
